Popis:	In the Y 2 O 3 :3Al 2 O 3 :4B 2 O 3 system infrared absorption spectroscopy and X-ray diffraction have been used to study the solid-state reactions in the 600–1300°C temperature range. The expected YAl 3 (BO 3 ) 4 formation (whose optimum temperature is at about 1150°C) was proceeded and accompanied by the appearance of YBO 3 and Al 4 B 2 O 9 intermediate phases. At higher temperatures the Al 18 B 4 O 33 phase was also identified with both methods. Based on these results, some chemical reactions were suggested.
